Spieth's feat did not go unnoticed by 18-times major winner Jack Nicklaus, who tweeted: "Great display of guts, determination and skill. Well done @JordanSpieth!!! #TheOpen".

And three-time Open champion Tiger Woods was also quick to pay tribute, taking to social media to write: "What an incredible way to comeback and win. Many congrats @JordanSpieth".

Woods' former coach Butch Harmon was also impressed, telling Sky Sports Main Event: "I don't know what to say - it's phenomenal - and he's only 23 years old." He then found some words, and added: "This kid is special. When he goes home tonight and takes his shirt off, there's an 'S' on his chest - he's Superman."

Ex-European Ryder Cup captain Paul McGinley struggled to hold back the superlatives, telling the channel: "It's one of the greatest performances I've ever seen - and I don't say that lightly - in any sport."
